of steam.

We have shown. and described vwhat we believe to be the* simplest andV best. embodiment of our invention, which has' beenl described in terms employed merely asterms of description and not as terms of limita-l tion, as modifications are possible and'. may be` made: without, however, departing from thev ,sf irit ofV our invention;

t we claimy is:

transverse interior wall of comparative thiekness-,.said wally being centrally provided witlrran'y opening therethrough of predetermined diameteig-thev side walls of the member at points coincident with saidtransverse wiall being providedwit'h a plurality of ports arranged in a` circumferential row about said central:` openingY andi inclining upwardly toward; the interior of the member.l said ports terminating on the interior of the ,memberadjacent to the upper end ot' lsaid 2'. A b ower nozzle for locomotives oomprising al tubularV member having a relatively thick' wal'l at the lower end which is bored wardly at` a: point Y LA blower nozzle for locomotives coml pnisng' a. tubular` member. provided with acentrally to leave a transverse wall adjacent to the lower end, said transverse wall having a comparatively small central opening therethrough of predetermined diameter for effect'ing communication between the lower bore and the interior of the member above the transverse wall, a circumferential row of ports in the side walls of the tubular memer disposed inwardly and upwardly from a point coincident with the transverse wall and; terminating at their upper ends adjacent'. to the upper surface of the transverse wall` inv close proximity to the upper end' of said centrali. opening.
